#introduction though I'm not new here, but moved to my #selfhosted #Mastodon instance half a year ago 
.
I'm Florian 
, #IT/computer science student at #RWTHAachen 
and #tech enthusiast.
I do lots of #selfhosting in my #homelab, develop apps with #Flutter 
, but also websites 
and other #software 
.
I'm very passionate about emergency #medicine 
and work as a #paramedic (Rettungssanitäter ) on the #ambulance 
in #ems 
.
I love water sports, be it #sailing 
, #diving 
or #swimming 
.
Ich bin nicht #neuhier, aber vor gut 1/2 Jahr auf meine #selfhosted #Mastodon-Instanz umgezogen .
Ich bin Florian , #Informatik|student an der #RWTHAachen und #tech-Enthusiast.
Ich hoste vieles im #homelab #selfhosting, programmiere Apps mit #Flutter , aber auch Webseiten und andere #Software .
Zudem begeistert mich die #Notfallmedizin #Medizin und ich bin als #Rettungssanitäter im #Rettungsdienst tätig .
Ich liebe #Wassersport, egal ob #Segeln , #Tauchen oder #Schwimmen .
So, my conclusion after tinkering with "docker compose" and Synapse for a few weeks, is that you're really not meant to access network services on the Docker host (like Postfix) from a container.
("docker run" is a different story, but less relevant for my use case.)
I haven't seen a single working example of this (no socat please). So, either I'm really bad at reading, or nobody is doing it this way successfully.
An SSD failed in my media server today. In case you are curious this is how I keep track of what I did, when, and why to my fleet of machines.
The backlinking in Obsidian is crucial for this format to work.
@gytisrepecka I mean ya gotta raw-dog it if you're going all-in when #selfhosting
"it's not self hosting if it's behind a CDN" is a bullshit take.
(Should probably be #fastly instead of #cloudflare )
You can build and run open source software on your own domain and I'd call that self hosting.
Run it on a good VPS? Still self hosting even if you can't rent a rack in a datacenter or don't own fast Internet.
Your #selfhosting is still valid as long as you administer it and it's not the big socials.
What’s the state of the art in SMTP servers these days? I see so many boosts of “what’s the secure alternative email server” questions, and self-hosting still seems overly hard. Contrast to the eleventy billion ways to host web sites and dynamic content…
Sweet. Got my Matrix server configured properly now, so the Element Android app connects to it, and it federates with matrix.org.
Time to start hacking on some ideas for an ND-friendly chat app.
So the #synology X25 refresh lineup just popped out. Should be arriving in May.

Nothing major apart from network and RAM upgrades. Steady as always
How to describe the #PiHole experience?
The other day my spouse called me to ask if I think her work PC could be infected. Took me a moment to connect the dots.

After asking here about decentralized/self-hosted chat options akin to Slack and Discord, I started playing with Matrix last night.
Got my own server up and running pretty easily.
A friend and I have been kicking around ideas for a chat app with a customizable and flexible UI that can be tailored to your communication and thinking style, allowing for deep threads and cross-linking of threads and messages.
Almost like a mindmap, in a way, but for communication.
So many communication tools force us into a linear way of thinking and communicating, and I'm curious to explore what a non-linear communication tool could look like.
Will start into Sonic 2 again later this day and try to beat my PB in Metroid Dread once again tomorrow. 
Friday I will boot up my NTSC-J copy of Final Fantasy X International on my PAL PS2 with Matrix chip, using my new OSSC Pro.

Need assistance with reproducable server
Hello server/hosting/devops/sysops fedi! 
I've enjoyed using NixOS. I like it because it allows me to recreate my server very easily when moving hosting providers. I don't want to bind myself to a hosting provider because it's an instance of vendor lock-in.
However, when using NixOS, I've often experienced that support for certain newer services (e.g. Dendrite) was not good (and writing Nix unfortunately feels very inaccessible and unintuitive to me). Also, there was no way to make sure I wasn't using compromised packages (since vulnix was discontinued), making my server vulnerable to CVEs and supply chain attacks.
Guix' Scheme language feels very verbose and cumbersome to read to me, so I'm not sure I want to go that route either.
Therefore, my question is: Can I get the reliable reproducability of NixOS with a different tool or set of tools as well? Ideally without the cons mentioned above, of course. :)
Thank you for your time!

I’ve got a bunch of the Chromecast Audio devices around the apartment. Incredibly useful little things. But still, tied to the cloud. #SelfHosting #SelfHosted
Yet another reason I’m trying to make everything local-first.
